In a multisite install with WordPress 4.0, Buddupress 2.1.1, the twenty-thirteen theme and all plugins disabled, I am adding the WP visual editor to message pages through the following function in the mu-plugins folder:

function enable_visual_editor_in_buddypress_messages( $editor_text ) {
    ob_start();
    wp_editor( '', 'message_content', array(
		'textarea_rows' => 15,
		'teeny' => false,
		'quicktags' => true,
		'drag_drop_upload' => false,
		'media_buttons' => false,
		'tinymce' => array(
			'toolbar1'=> 'bold,italic,underline,blockquote,hr,link,unlink,undo,redo,image,emoticons,wp_help',
			'toolbar2'=> ''
			),
		)
	);
	$editor_text = ob_get_contents();
	ob_end_clean();
	return $editor_text;
}

add_action( 'bp_before_messages_compose_content', 'enable_visual_editor_in_buddypress_messages' );

add_action( 'bp_before_message_reply_box', 'enable_visual_editor_in_buddypress_messages' );

The editor loads and it works, but it is missing most of the div wraps and classes of a normal implementation (for instance adding the same function to WP comments).

After digging around a little, I found out that the editor is not loaded normally through the wp_editor() function in the general-template.php (as happens in the WP comments), but instead BP calls directly the editor_js() function in class-wp-editor.php.

Another consequence of this is that if you set quicktags to true, the visual tab and functionality disappear completely and you just get a textarea with the quicktags buttons above and no other html markup before and after.

Any idea why this happens and how can it be amended?
